JOHN swIERGocKI, or CHICAGO, ILLINOIS.

SOLDERING-IRON.

Application filed August 21, 1914.

To all whom it may concern Be it known that I, JOHN SwInRsooKI, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Soldering-Irons, of which the following is a'full, clear, and exactspecification.

This invention relates to soldering irons and has for its object aconstruction which includes an adjustment whereby the intensity andstrength of the flame and resulting heat may be regulated.

WVith the above and other objects in view this invention consists in theconstruction, combination and arrangement of parts all as hereinaftermore fully described claimed and illustrated in the accompanyingdrawings wherein:

Figure 1 is a side elevation of an iron con structed in accordance withthe present invention, illustrating a substitute handle in dotted lines.Fig. 2 is a longitudinalsection along line 22 of Fig. 1 to illustratethe arrangement of the iron tip in connection with the fuel and airfeeds. Fig. 3 is a vertical section along line 33 of Fig. 1 and constitutes an elevation of the inner end of the soldering tip or point,the feed pipe being in section. Fig. 4 is a similar view along line 4-4of Fig. l to illustrate the air feed regulator.

Reference being had to the various figures 10 designates the solderingpoint or tip which is socketed at its inner end to form a heatingchamber 11. The wall of this socket is provided with a number of groovesor channels 12 that constitute a discharge for combustion products. Afeed pipe 13 is inserted in the socket or chamber 11, being held inplace by friction due to shrinking or a similar process, and is adaptedto deliver a mixture of fuel and air to the chamber 11 for action, whenignited, on the soldering tip or point 10.

A casing 14, inclosing the mixing chamber 15, is threaded on the outerend of the feed tube 13, and has a bafile plate 16 formed thereon, toact as a shield from the heat radiating from the point or tip 10. Theouter end of the casing is closed by a perforated partition 17, saidpartition being provided with an interiorly threaded concentricSpecification of Lett'e'rs'iPatent.

aperture 18 through which the fuel supply pipe 19 extends. This supplypipe 19 is threaded as at 20 for engagement with the threads of theaperture, whereby the said pipe may be adjusted with respect to thecasing 14 and its projection into the chamber 15 thereof. At the innerend of the supply pipe 19 is a nozzle 21 through which the fuel isdelivered to be mixed with the air and directed to the feed pipe 13.

Loosely mounted at the outer end of the casing 14 for cooperation withthe perforated partition 17, is a closure plate 22, having theperforations 23 for registration with the perforations 24 of saidpartition. An ear 25 is formed from the closure plate 22 and constitutesa means whereby the plate may be oscillated to register the perforations23 and 24 or to break such registration, thereby increasing ordecreasing the supply of air to the mixing chamber 15. In order to limitthe oscillatory movement of this plate 22 a headed pin 26 is-secured inthe partition 17 and projects through an arcuate slot 27 formed in saidplate.

A continuation 28 of the supply pipe 19 may be curved or straight and ineither event is embraced by the handle 29. Connecting with thiscontinuation 28 is aflexible tube 30 by means of which the fuel isdelivered to the supply pipe 19.

In operation the passage of the fuel from the nozzle 21 draws air intothe mixing chamber 15 through the registering perfora tions 23 and 24,and to decrease the air in the mixture the registration of theseperforations may be broken to any desired degree, by the oscillation ofthe plate 22. By rotating the pipe 19 the position of the nozzle 21thereof with respect to the feed pipe 13 will be adjusted by means ofthe cooperation between the threads 20 and the threaded aperture 18.

What is claimed is: c

In a device of the class described, a soldering tip having a socket atits inner end forming a heating chamber, the walls-of said chamber beinggrooved to provide discharge openings for the products of combustion, afeed pipe having one end fitted in the socket and the opposite endscrew-threaded, a casing screwed upon said screw-threaded end and havinga peripherally flanged heat shield and an interior mixing chamber, aperforated affixed my name in the presence of two witpartltlon at oneend of sald chamber havlng nesses. a central aperture, and a SBIIBS'Ofair inlets,

a fuel supply pipe extending through the JOHN'SWIERGOLYKI" 5 centralaperture and a perforated oscillatory Witnessen plate controlling theair inlets. RoB'r. Know,

In testimony whereof I have hereunto VIOLA HARTMAN.
